HS17 has 7 usable tuners equal to 3.5 HR2X’s, so unless you have more then three HR2X’s you don’t lose anything on the tuner front. IMHO the biggest issue is the single point of failure of the Genie 2 system.
i said a had a genie and an hr24, thats the same 7
once you hit 3 tvs it would be 9, still 7 with an hs17
many people have a genie and a dvr
cant do that with the hs17, the 7 tuner hard limit with 1 subtracted for each mini in use is what cripples it
if you have 1tv it would be fine.
2 its borderline depending on needed tuners
3 and its not even a choice
